\frac{2\pi}{3} radians is equal to 90°.

Step-by-step explanation:

Step 1:

If an angle is represented in radians, it will be of the form \frac{\pi}{x} radians.

If an angle is represented in degrees, it will be of the form x°.  

To convert radians to degrees, we multiply the radian measure by \frac{180}{\pi}.

For the conversion of radians to degrees,

the radians in degrees = (given value in radians)(\frac{180}{\pi}).

Step 2:

To convert  \frac{2\pi}{3},

\left(\frac{2 \pi}{3}\right)\left(\frac{180}{\pi}\right)=(2)(60),

(2)(60) = 120.

So \frac{2\pi}{3} radians is equal to 120°.

White raven [17]

Answer:

I am having a hard time reading the letters, so I hope this makes sense.  I think that the numbers for the top triangles is given is 6 and 3.  That means that the scale factor from the little to the big is 2 and from the big to the little is 1/2.  It is the same for the bottom triangles.

Step-by-step explanation:

If the triangles are similar the scale factors will be the same for all three corresponding sides of the triangle.  You find the two sides that are corresponding and ask yourself what do I have to multiple the side of of triangle to get the new triangle.  

If one side is 3 and the other triangles side is 6.  I am asking myself what do I have to multiple 3 by to get 6?  2.  That is my scale factor.

3x = 6

x = 2

The scale factors are always reciprocals of each other.  If I go the other direction I can write the equation

6x = 3 and when I divide both sides by 6, I get a scale factor of 1/2.

The bottom triangles:

2.5 x = 5

x = 2

and

5x = 2.5

x =1/2

Solve the following equation for x: 6x-16=14
Ivenika [448]

To solve the equation for x, first, we add 16 from both sides of the equation:

\begin{gathered} 6x-16+16=14+16, \\ 6x=30. \end{gathered}

Now, we divide by 6:

\frac{6x}{6}=\frac{30}{6}.

Finally, we get that:

x=5.

Answer:

x=5.
